BLE OTA hex files example

[dilbert168]

I try to get the BLE OTA procedure working using the nRF52-DK board.

1. Using the pre-build example hex files in folder "nRF5_SDK_17.0.2_d674dde\examples\dfu\secure_dfu_test_images\ble\nrf52832"

2. Load example hex file "sd_s132_bootloader_buttonless_with_setting_page_dfu_secure_ble_debug_without_bonds.hex"

3. Downloading (DFU) the "hrs_application_s132.zip" using the nRF Connect on Android phone

    --- working OK.

However, when I try to load individual hex files (i.e. App, SoftDevice, Bootloader) individually

- after loading bootloader_secure_ble_debug_without_bonds_s132.hex

- Following sections are missing : 

      0x7E000 - MBR parameter storage

      0x7F000 - Bootloader settings

- After programming all hex files using nRF desktop programmer, the bootloader only jump to "DfuTest" and not start App.

Questions : 

1. What are the steps I have missed ?

2. Where I could find the source code for creating  "hrs_application_s132.zip" ?

Hi, 

1. It needs to program the Bootloader settings page, then the bootloader can boot the application. For information on creating a valid bootloader settings page, see Generating bootloader settings.

2. See the Heart Rate Application example under <InstallFolder>\examples\ble_peripheral\ble_app_hrs. 

Regards,
Amanda

2. I tried build and loaded the <InstallFolder>\examples\ble_peripheral\ble_app_hrs.

onto nRF52-DK board using SEGGER.

but when pressing any Button, the debugger will stop at "NRF_BREAKPOINT_COND"

Checking the code in main() bsp_event_handler(), I don't see any handling for KEY
